# Monoammonium Phosphate Fertilizer 12-61-0

### **Monoammonium Phosphate (MAP) 12-61-0**

Maximize root development and flowering with **Monoammonium Phosphate (MAP) 12-61-0**. As a technical-grade, 100% water-soluble fertilizer, it is one of the most highly concentrated liquid-ready phosphorus sources available. Delivering a massive 61% available phosphate (P₂O₅) and 12% ammoniacal nitrogen, it dissolves completely and clear, leaving absolutely zero residue.

The powerful dose of phosphorus drives robust root growth, prolific flowering, and reliable fruit set. Meanwhile, the ammonium-form nitrogen gently acidifies the root zone to ensure the phosphate remains easily absorbable by the plant. This mildly acidic solution makes it exceptionally beneficial in alkaline and hard-water soils where phosphorus typically locks up.

**Ideal For:**

-   **Drip Irrigation & Fertigation:** Engineered to dissolve crystal clear without clogging emitters.
    
-   **Hydroponics:** A highly effective, clean nutrient source for hydroponic reservoirs.
    
-   **Targeted Feeding:** Excellent for banded liquid starter applications and foliar correction.
    

**Key Features:**

-   **Maximum Concentration:** Delivers an incredibly potent 12-61-0 NPK ratio.
    
-   **100% Water-Soluble:** Technical-grade formula leaves zero residue behind.
    
-   **Tested & Certified:** CDFA registered and rigorously third-party lab-tested for heavy metals, consistently testing well below required limits.
    

**Important Handling & Application Rules:**

-   **Choose the Right Grade:** This is the _water-soluble_ grade designed for dissolving. If you plan to dry broadcast on fields, lawns, or garden beds, granular MAP 11-52-0 is the appropriate choice.
    
-   **Crucial Mixing Rule:** In hydroponic and fertigation setups, keep MAP separated from concentrated calcium and magnesium fertilizers. Combining them in a concentrated stock will cause precipitation—always run separate stock tanks.
    
-   **Application Best Practices:** Always check your solution's pH after mixing. For foliar applications, spray only in the early morning or late afternoon.
